Definitions
- the invention relates to a semiconductor integrated circuit with pad cells and a method for checking their function.
- Integrated semiconductor circuits have pad cells that are composed of a connection pad with a flat Connection area for external leads and one upstream output driver.
- the external supply lines serve to exchange data or signals between different Circuits or assemblies in the pad cells integrated output driver for digital output Signals on the external feed lines.
- These output drivers need for reliable operation of the integrated Circuit and the modules connected to the circuit in their functionality, especially with regard to the transmission behavior of signals, precisely specified requirements are enough.
- the object of the present invention is an integrated Specify semiconductor circuit with pad cells with which a functional test of the pad cells with regard to their transmission behavior with a relatively small apparatus Measurement effort can be made, and also a method to be specified for carrying out the functional test.
- the integrated circuit according to the invention has a signal generator to generate periodic signal sequences whose periodic output signal in a test mode an input fed to a pad cell to be tested as an input signal is. By loading the pad cell with one periodic signal can be an external measurement at the output the pad cell in the frequency domain.
- a measuring arrangement is used with the integrated circuit, with which a measurement of the frequency spectrum is carried out is characterized by the dynamic behavior of the pad cell can be.
- the detection of harmonics up to fifth harmonic is sufficient and the mutual frequency spacing between these harmonics is relatively large the requirements for the resolution of the measurement in the frequency domain and thus the equipment of the measuring device is low being held.
- the signal generator is reprogrammable to generate various periodic signal sequences. So there is the possibility the measurement of the characteristics at different speeds adapting switching pad cells, for example by a Signal sequence with a short period of time at proportionate fast switching output drivers and a signal sequence with longer period with relatively slow switching Output drivers.
- the inputs of the Pad cells to be tested in parallel with one or more connections connected for the output signal of the signal generator be, or in series via, for example, each a slide register cell with a connection for the output signal of the signal generator be connected. In this way, all the pad cells to be tested get the same input signal delayed by one clock period.
- FIG. 1 shows in the upper part an arrangement for functional testing of a pad cell PC of an integrated circuit.
- This arrangement is intended to characterize the transmission behavior of the output driver of the pad cell PC in a test mode.
- a digital signal U E equal to a step function from a low signal level to a high signal level is applied to the input E of the pad cell PC (connection for the input signal of the output driver) and the signal curve of the signal U DQ at the output DQ of the pad cell PC (Connection for the supply line to be connected to the connection pad) measured.
- This signal curve characterizes the dynamic behavior of the pad cell PC, which can be simulated using an equivalent circuit diagram with model parameters.
- An exemplary circuit diagram of an output driver of a pad cell PC with the model parameters R D1 , R D2 , L, C is shown in FIG. 2.
- FIG. 1 a simplified course of the so-called step response of the signal UDQ, caused by the step function of the signal UE, is shown.
- the voltage level of the signal UDQ does not suddenly jump from the switch-on time t1 to the value U H in the steady state, but rather more slowly in a dynamic course according to the values of the model parameters R D1 , R D2 , L, C, characterized by the current constant ⁇ .
- their size depends on the values of the model parameters R D1 , R D2 , L, C.
- the functionality of a pad cell PC in Figure 1 is that the voltage level of the UDQ signal between a minimum time tmin and a maximum time tmax from the switch-on time t1 has a value that is in the tolerance range between a minimum value Umin and a maximum value Umax lies.
- the course 1 of the signal UDQ shows an example Step response of a functional pad cell PC.
- the course 2 of the signal UDQ shows an exemplary step response a faulty pad cell PC.
- the time between tmin and tmax in the current state of development a few 100 ps, which means that they are comparatively high Requirements placed on the measuring accuracy of the measuring apparatus.
- Figure 3 shows a circuit arrangement with a signal generator SG for generating periodic signal sequences.
- a signal generator SG for generating periodic signal sequences.
- DQ is also periodic
- This Course can be in a measuring process with one at the exit DQ from externally connected measuring arrangement SAZ, which for A spectral analysis is suitable, for example with a so-called spectral analyzer and by analyzing the recorded frequency spectrum be characterized.
- the pad cell PC was characterized by the model parameters R D1 , R D2 , L and C.
- the resistors R D1 and R D2 model the forward resistances of the switching transistors T1 and T2, L the lead inductances and C the lead capacitances.
- the values of the previously set model parameters of the pad cell PC are determined in succession in a known manner (for example by means of a Fourier analysis) on the basis of the frequency spectrum, which comprises the amplitude response and / or the phase response, and the step response of the pad is derived therefrom -Cell PC calculates, which provides information on whether the criterion for functionality is met.
- the step response using the known analysis methods directly on the basis of the frequency spectrum, without first setting up an equivalent circuit diagram with model parameters.
- the number of harmonics of the frequency spectrum to be determined depends essentially on the number of installed Model parameters.
- This is enough Determination up to the fifth harmonic for a sufficient Accuracy. Since only these harmonics are detected, their mutual frequency distance compared to the harmonics from the fifth harmonic is relatively large, the effort remains the measuring apparatus with regard to frequency selectivity relatively small and is therefore significantly smaller than one described measurement in the time domain.
- the step response is calculated by the time constant ⁇ , which corresponds to the values the model parameter is calculated.
- the line inductance L and the load capacitance CL and line capacitance C can be neglected in relation to the forward resistances R D1 , RD2 of the transistors T1 and T2.
- the measurement in the frequency domain can thus be replaced by a simple direct current measurement at the output DQ. From the values of the supply voltage VCC or VSS and the currents I1 and I2, the resistances R D1 and R D2 can be calculated and, as mentioned above, the step response of the signal UDQ. To carry out this measurement, however, it is necessary to increase the period of the stimulating input signal UE so that a quasi-steady state arises at the output DQ for each measurement of the currents I1 and I2.
- the period of the signal UE can be changed, for example, by reprogramming the signal generator SG using an external control signal BS of an operating mode control.
- a multiplexer circuit MUX provided, for example by the signal BS Mode control is controlled. Another entrance the multiplexer circuit MUX next to the first input, to which the output signal of the signal generator SG is present each for a signal to be output in normal operation 0 to n another functional unit of the integrated circuit intended.
- FIG 4 shows a further embodiment of the invention Circuit.
- connections E for the Input signals of several pad cells PC to be tested serial via a clock-controlled shift register cell FF0 to FFn with a connection A for the output signal of the signal generator SG connected.
- each pad cell PC is delayed in time by one clock period of the shift register cells FF0 to FFn the periodic output signal of the signal generator SG on.
- This embodiment is advantageous for circuits where the pad cells PC are already used for other purposes connected to each other via shift register cells FF0 to FFn are (e.g. for printed circuit boards with "boundary scan").
- the shift register cells FF0 to FFn and the signal generator SG can be used, for example, with clock-controlled bistable Realize flip-flops.
- the signal generator SG for example a T flip-flop with a permanently connected input act
- the shift register cells FF0 to FFn can for example with D flip-flops.
- the signal generator SG and the shift register cells FF0 to FFn make sense controlled by the same clock.
- the T flip flops are as described above, advantageously carried out so that the respective periodic output signals by reprogramming can be changed.
